Vanishing Frigate

When building a custom blueprint from history that no longer exists / has been upgraded, the ship vanishes instead of being built

I was building a ship on my starting planet, surrounded by military outposts on all sides , and it should have been 1 turn to build the custom frigate blueprint that no longer existed ( because the blueprint had been upgraded, but was still offered in the history of what the planet built previously ). Instead the ship seemed to vanish after 1 round.
